A housing for an electro-magnet comprising a single piece structure consisting of a base and sides rising therefrom, certain of the sides being connected with the base by doubled portions forming laterally-exv70 tending flanges at and in the same plane with the base, said flanges having fastening receiving apertures, whereby the housing. may be secured to a support.

2. A housing for an electro-magnet com- 75 prising a single piece structure consisting of a base and sides rising therefrom, certain of the sides being connected with the base by ,doubled portions forming laterally-extending llanges at the base, whereby the hous- 8o ing may be secured to a support, in combination with a core fastened to the base, a magnet assembled on the core, and internal flanges on the sides of the housing to engage the Referring particularly to Figs. l and 2 it will be noted that the tongue 28 is bent downwardly beneath the body portion 25a and is adapted to come'adjacent a contact 5 point 32 carried on an adjustable screw 33 which is insulatingly mounted on a support 34. This support 34 is formed integrally with the housing blank, and is indicated in Fig. 4 as lying adjacent the line of bending y, said support being provided with an opening 35 adapted to receive the said adjustable screw 33.

In order to maintain the end of the tongue or movable contact 28 in engagement with the contact point 32 a helical spring 36 is employed, one end of which engages the outer end of the armature 22, the other end of which is secured in the said support 34. As a further means of determining the movement of the armature relatively to the electro-magnet the tongue 27, formed in the blank fromwhich the armature is made, may be bent downwardly into the position 'shown in Fig. 2, and may be entered into the opening 37 formed in the side l2 of the housing, the location of the said openin being shown in Fig. 4. The upper end of the opening 37 forms a stop or abutment with `which the tongue 27 engages to limit the 30 movement of the armature away from the core under the tension of thespring 36. l

y or all of the sides may be provided with openings 38, if so desired, adapted t0 conduct the wires 39 leading from the electro-magnet exteriorly of the housing, where they may be secured to suitable studs 40 carried on an insulating plate 41 fixed to the side of the housing in any desirable manner, as by means of lugs 42 formed integrally he combination of a housing, an electro-magnet therein, an armature pivoted on the housing, a tongue on the armature, an opening in the side of the housing forming an abutment with which-the tongue engages ing on the armature to oppose the movement of the same toward the magnet.

4. A housing for an electro-magnet comprising a sheet metal structure consisting of a lbase and four sides, two of the sides being directly connectedwith the hase and the other two sides being connected with the base by lateral extensions, internal 10o flanges on the said sides coperating to form an internal flange extending entirely around the structure, an electro-magnet mounted in the structure and of such axial length as to engage under the flanges with the magnet, resting on the said base, an armature secured to the said structure and forming a cover for the same over the magnet, a circuit make-and-break device consisting of members on the said structure and armature respectively, and a spring connected with the said structure and armature for holding the said -Inembers in engagement.

5. A, housing for electro-magnets comprising a casing open at the top, an armature pivoted on the casing and consistingf of a plate-like body having oppositely-projecting extensions, tongues struck out from the extensions, an abutment on the casing with which one tongue engages for limiting the movement of the armature, a fixed =rontact on the casin for engagement with the other tongue to orm a circuit make-andbreak device, an electro`magnet in the casing, and a spring connected with the armature to op- 126 posethe movement thereof by the electromagnet.

6. The combination/of a housing consisting of a base and sides, said basevextending outwardly from the sides, a tongue struck 130 4l are other studs 43 which may be integral with the first studs 40, and which serve as a connection for the circuit wires leading to the electro-magnet. .v 45 If so desired, the interior of the Housing may be lined with any suitable material, suc as insulation or Waterproof material. 'lhe housing illustrated and described is merely one of many forms which the idea 50 may assume, the use of such a housing not only preventing injury to the winding of the electro-magnet, but at the same time increasing the efficiency of the said magnet, due to the fact that an iron circuit is proend of the core to a location adjacent the upper end of the said core. The structure is exceedingly simple and may beformed by stamping, the subsequent act of bending be` dies, all of which tends to economical construction. Y
